- _constants.py: ALARM_DAYS now every day (was Mon/Fri/Sat/Sun); DISMISS_CODE_LENGTH 8->10 and DISMISS_ROUNDS_REQUIRED 2->4 so dismissing forces staying awake longer. - _challenges.py / _alarm.py: expanded dismissal challenge logic, with matching test updates. - shutdown-wrapper.sh: updated hibernate/rtcwake wrapper. - .gitignore: restore the missing rule for wake_alarm/wake_state.json (HMAC dismissal runtime state — must never be tracked, per CLAUDE.md). Tests: 191 passed, 100% coverage. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017RRCdR4D8SaVrN2xraMQxM

# Wrapper for /usr/bin/shutdown that redirects to rtcwake -m disk on alarm
|

# nights (every day of the week). This ensures that both the automated
|

# systemd timer AND manual "shutdown now" hibernate correctly so the PC
|
|
# wakes for the morning alarm.

|

# because /usr/local/bin appears first in PATH).
